Child Script

[torels]

Hi there

I'm working on a project where I need to return a value to a script other form the script where the function returning the value is in, and the "child" script isn't included in the "parent" one.

Is there any way to return values using Return ?

since my english isn't wonderful, i'll make a simple example: Script A.au3 runs script B.au3, and I want a value to be returned from script B.au3 to script A.au3

thanks in advance

Lots of ways. Here is one

script 1. Compile this as exit1.exe and save it in the same folder as the next script

ControlSend("1997aggh","","[Class:Edit;Instance:1]",536)

then run this script

$rf = GUICreate("1997aggh")
$ed=GUICtrlCreateEdit("",0,0,100,100)
Runwait("exit1.exe")

ConsoleWrite(GUICtrlRead($ed ) & @CRLF)

But it depends on what you want to send back.

thanks for the example but I wanted to use return

Script B is a user-created script (created after script A is compiled) And I wanted it to return values like if the function was in the script, so using Return. Also, script A has no GUI.

I was also thinking of a function override (i think that's the word) so to create a "Return" Function acting like Return... but i don't think it's possible...

any other suggestions ?

Maybe an example of something you would like to do would help.

Do you mean that you want the second script to act as a function and return some result? In which case the method I showed would work but so would others.

My example was just to show a way to pass information very simply without a visible gui, but you could also use messages for example.

Dlls act as external functions but you cannot create them with AutoIt.

Perhaps the child script could end with:

$iRetVal = 1234 ; Some meaningful INT32 value
Exit $iRetVal

The the parent script would call it with:

$iRET = RunWait($sPathToChildScript)

Only good for INT32 values, but you haven't been very clear about what data you want to pass back.

Another way is to store and read the data in a file.

Second script writes the data , first one reads the data after script 2 finishes.

You can store in INI files - there a a lot of helpful ini functions you can check in the help file.

Yet another way would be to use the MailSlot UDF - very simple to

use and works great. (You can tell I'm a fan???)

@Juvigy & dmob: I now there are many methods. The point of my question was, as I said, that the script returing the value is User-Created after the script recieving the value is compiled. So I needed to keep it as simple as possible so to use any script without any particular changes.

Thanks for the help anyway

@PsaltyDS: Thanks for your help, I suppose it's the easiest way of doing it
